Ski/Sea Plane Operations

C185 1980 with pPonk.
We changed from McCauley to MT.
53lbs excluding the spinner.
Weight and CG was the reason.
Thrust about the same, probably a little more.
On a Scout on Amphibs we run a MT as well.
Never needed to files those little spray holes you get on aluminium props

I see MT has an STC for the Pponk dash 50 C180 combo.
I have heard of issues with forward CG with the big heavy Mccauley 3 blader.
So forward weight reduction vs thrust vs cost.
Anyone here have any stories of Pponking a 180 seaplane and which prop works best?
cheers & thanks...
